The Fragile Internet: AWS Outage, Undersea Cables, and Global Vulnerabilities

The AWS Outage and Internet Vulnerability

• 💡 The recent AWS outage highlighted the fragility of our interconnected world and the vulnerability of the internet.
• 🎯 Services like Snapchat, Roblox, and OpenAI were affected, impacting everything from banking to flight deals, demonstrating how dependent we are on cloud infrastructure.
• ⚠️ The outage occurred due to a disruption at Amazon Web Services, which provides approximately 30% of global cloud infrastructure.

The Physical Infrastructure of the Internet

• 🌐 The internet, initially conceived as decentralized, now relies heavily on physical infrastructure, including data centers clustered in specific regions like Northern Virginia.
• 🌊 Undersea cables, dating back 150 years, carry 95% of all international data traffic, with fiber optic strands as thin as a human hair encased in cables no thicker than a garden hose.
• 💰 While the cost per gigabyte has decreased, laying these cables is still expensive, with a UK-US transatlantic cable costing around half a billion dollars.

Concentration of Power and Ownership

• 🏢 Initially built by telecom consortiums, undersea cable construction and ownership have shifted to big tech giants like Google, Meta, Amazon, and Microsoft.
• 🇺🇸 These four companies are all American, leading to a concentration of power and vulnerability to US government pressure.
• 🌍 This ownership structure reflects historical patterns of wealth and power, leaving regions like Africa significantly underserved by internet infrastructure.

The Tonga Outage: A Case Study

• 🌋 The volcanic eruption in Tonga severed the island's single international undersea cable, causing a near-complete internet blackout for months.
• 🚫 Effects included inability to access ATMs or banks, communication breakdowns, and even the failure of internet-dependent devices like solar panels.
• ⏳ Repairs for the main island took nearly five months, while a domestic undersea cable break took 18 months to fix, highlighting the long lead times for specialized repairs and manufacturing.

Geopolitical Risks and Future Concerns

• ⚠️ Countries like Taiwan, with multiple undersea cables and geopolitical vulnerabilities, face risks of sabotage, particularly from rivals like China.
• 🇬🇧 Even the UK is increasing patrols to safeguard its undersea infrastructure, recognizing the potential for disruption.
• 🇨🇳 The geopolitical tension between the US and China is leading to a bifurcation of the internet, with separate cable routes and potential for fragmented networks.

Solutions and Layperson Concerns

• 🔌 Simple solutions involve laying more cables along geographically diverse routes and landing in multiple cities, not just traditional hubs.
• ⚡ Addressing power demand for data centers and AI is crucial, alongside more complex technological solutions to diversify the internet's structure.
• 🤔 While daily users may not experience cataclysmic outages, the lack of internet access is a significant livelihood issue for millions globally, underscoring the need for broader connectivity.
